The main idea here is recognizing which symptoms are typically seen in a systemic allergic reaction, especially the more urgent, reaction-wide signs, versus those that are more limited to a runny-nose type allergy. In a systemic allergic reaction, you’d expect signs that reflect widespread effects of histamine release: swelling of the lips and face (angioedema), a rash or hives, and sometimes pale or flushed skin from changes in blood flow or early shock. These are common, regarding the body-wide response.

Sneezing, on the other hand, is mainly a nasal symptom associated with allergic rhinitis or milder, localized allergic irritation. It doesn’t by itself indicate a systemic allergic reaction. So while sneezing can occur with allergies, it’s not listed as a common sign of a systemic allergic reaction in the context of recognizing urgent reactions, which is why it’s the item that doesn’t fit with the other symptoms.
